个人简介

Heisenberg-Fellow of the German Science Foundation, 2005-2007 2014 UTA Outstanding Faculty Advisor 2014 College of Science Outstanding Research Award B.Sc. (physics and mathematics, "Vordiplom") University of Heidelberg, Germany (1989) M.S. (theoretical particle physics, "Diplom") University of Heidelberg, Germany (1993) Ph.D. (computational materials science) University of Technology Darmstadt, Germany (1996) Postdoctoral Fellow (chemistry), Cornell University (1997-99) Habilitation (Inorganic Chemistry) RWTH Aachen University, Germany (2005) Peter Kroll joined the Department of Chemistry and Biochemistry at The University of Texas at Arlington (UTA) in Fall 2007 as an Assistant Professor. He came from RWTH Aachen (Germany) where he was a Heisenberg-Fellow of the German Science Foundation since 2005. In 2011 Peter received tenure and is currently Associate Professor. Peter studied Mathematics and Physics at the Ruprecht-Karls University of Heidelberg (Germany) and received his “Vordiplom” (equivalent to a B.Sc.) in both subjects in 1989. After a beautiful summer at the CERN, he completed his Physics-Diploma (Masters) in 1993 with a work in Theoretical Elementary Particle Physics. He moved to the Technical University of Darmstadt (Germany) into the Department of Materials Science to pursue his doctoral thesis. Under supervision of Ralf Riedel (TU Darmstadt) and David Pettifor (Oxford University) he combined experimental and computational methods to investigate silicon nitride and silicon carbonitride ceramics. In 1996 he concluded his Thesis with Distinction. With a research stipend from the German Science Foundation he went to Cornell University to work under supervision of Roald Hoffmann as a post-doc. By him he was introduced into Chemistry, its many varieties and its beauty. In 1999, Peter moved to RWTH Aachen to set up his own research group and pursue a Habilitation. He received his “venia legendi” in Inorganic Chemistry in 2005. Peter’s work focuses on Computational Chemistry of Solid-State Materials. His major fields of research are ceramics and glasses on one side, and high-pressure chemistry on the other side. He currently investigates ultra-high temperature materials for hypersonic flight, new anode materials for Li-batteries, hard coatings of nitride materials, and has keen interest in phase diagrams of nitride compounds and in mechanisms of phase transformations. His work is currently supported by the NSF and by DARPA.

研究领域

Our group works on various challenges in materials chemistry using computational methods and tools. For instance, we investigate structure and properties of amorphous ceramics and glasses. We generate random network structures of complex multicomponent systems while retaining well-defined chemical order around individual atoms. Subsequently, we compute various properties, including thermochemistry, elastic moduli, vibrational properties and NMR spectra, and compare them to experimental data (if available) or to extract information that supports and enhances experimental investigations. Combining expertise of structure modeling with interest in quantum dots, we embed nanoclusters in glass matrices and investigate phenomena that originate from a confinement of electrons or that are dominated by interface properties. In this area, we recently started experimental studies of SiC quantum dots, developing a method to synthesize large quantities of these particles. Another direction we pursue is high-pressure chemistry, where our curerent interest is in structural phase transitions, their mechanisms and barriers. We have some long-standing interest in new nitride compounds and their high-temperature/high-pressure phase diagrams.
